① What does blockchain mining mean?

"Mining", as the name suggests, is the action that can appear in our minds, which is digging in the soil with a shovel, but Now we no longer use shovels, but computers. Instead of digging in the soil, we dig in a pool of data, and instead of digging for physical objects like gold and coal, we compete for the right to keep accounts. 1. Mining is the process of confirming transactions in the Bitcoin system over a period of time and recording the formation of new blocks on the blockchain. These miners are called miners. 2. Mining is a bookkeeping process, miners are bookkeepers, and the blockchain is the general ledger. 3. The accounting rights of the Bitcoin system are decentralized, that is, every miner has accounting rights. Miners who successfully seize the accounting rights will receive new Bitcoin rewards from the system. Mining is the process of producing Bitcoins.

1. What does mining mean?

Ancient mining can be traced back to the selection of stone materials in the Stone Age. Later, with the rise of the metallurgical industry, mining and mineral processing technology gradually developed. This article introduces the aspects of open-pit mining, underground mining, tunnel support, rock crushing, tunnel ventilation, lighting, drainage, lifting, and mineral processing in ancient China.

Open-pit mining There are many surface outcrops, slopes or residual deposits of various metal veins or ore bodies. Therefore, open-pit mining became an important mining method in ancient times. Open-pit mining can be divided into excavation method and soil reclamation method.

2. Mining is the name for accumulated income from activities in Bitcoin.

Mining was brought about by the recent popularity of Bitcoin. Bitcoin is a virtual currency that can be exchanged for real currency. One of the ways to obtain Bitcoins on the Internet is to participate in related activities every day. These activities, like mining in online games, require slowly accumulating wealth in exchange for Bitcoins.

② How to make money by mining in the blockchain

The principle of making money by mining: PoW and mining.

In the beginning, Bitcoin could be mined using graphics cards, but in 2013, it was no longer possible to mine Bitcoin BTC using general-purpose computing programs for graphics cards. All Bitcoins are now mined using ASIC mining machines. ".

Similarly, the launch of Litecoin ASIC mining machines in 2014 also ended the history of Litecoin mining using graphics cards. The current digital currencies that graphics cards can "mine" are Ethereum ETH, Ethereum Classic ETC, and Zcash Zerocoin ZEC.

Graphics card "mining" is not a profitable business. In fact, the earlier you start, the higher the income will be, and the income will decrease as more miners and graphics cards are added.

To put it bluntly, buying a high-priced graphics card to enter "mining" will definitely kill you. Purchasing a professional mining machine is a more cost-effective choice. Nowadays, the indispensable tool for personal mining is a mining pool. The function of a mining pool is to gather a large number of mining machines to increase the computing power.Increase your chances of mining coins, and at the same time, the coins you can mine in the future will be evenly distributed to your account in advance.

Take Bitcoin as an example. If the entire Bitcoin network now generates a block every 10 minutes, this block contains 25 Bitcoins. Assuming that there are 10,000 people in the world participating in mining, then within these 10 minutes, only one lucky person will take away the 25 Bitcoins.

Others have nothing to gain. The principle of the mining pool is that everyone forms a team to mine and allocate according to the agreed distribution method, so that the miners' mining returns tend to be stable and the miners' risks are reduced.

In order to enhance the cost performance, you can also purchase some practical mining machines like Wanke Cloud, which can be used as ordinary hardware products and can also be used for mining, killing two birds with one stone.

(2) Extended reading on blockchain mining machine mining business

There are several core operations of blockchain transactions and digital currency:

The transaction network connected by decentralized databases is called a blockchain. All our clients (including mining machines) keep accounts together, confirm transfer transactions, and issue a certain amount of digital currency based on time.

Because the winner takes all, small and medium-sized retail miners have to unite to form a "mining pool" and record the cumulative workload in Shares. The higher the joint computing power, the greater the probability that the mining pool consortium will find the digital currency first. Large, increase the probability of finding newly issued digital currencies, and divide the mined digital currencies. This is called the PoW workload proof mechanism.

③ The essence of blockchain mining

Investment products are usually divided into debt products and equity products based on the certainty and uncertainty of returns and risks. Creditor's rights pursue absolute returns, while equity investors are willing to take risks and obtain floating returns. Usually these two are completely different products. However, the emergence of blockchain technology has made it possible to integrate these two types of products.

Take Bitcoin, the first concrete application of blockchain, as an example. BTC is released in mining mode. Every ten minutes, the mining machine that grabs the accounting rights is rewarded with 6.25 Bitcoins. Based on the current computing power difficulty, the output of a mining machine can be expected. Therefore, the income from short-term investment in mining machines is relatively certain, but due to the huge volatility and growth space of Bitcoin itself. The life cycle of a mining machine is more than one year. Investment in mining machines essentially requires a judgment on the future BTC capital value and risks. Bitcoin mining provides a new model of short-term deterministic returns and long-term floating returns.

The reason why this model was established is that first of all, everyone formed an initial consensus on the value of BTC and there was a secondary market for free transactions. The mined BTC can be traded and sold at any time to obtain deterministic returns, or it can be held as an asset for a long time to obtain long-term investment returns.

Equity investment fully embodies the capital spirit of sharing risks and sharing profits.

A sign of the mature development of the capital market is the richness of equity products and tools.

Chinese society is generally dominated by the creditor's rights mentality, and investment capital preservation is the basic expectation of most investors. On the one hand, this mode of thinking is due to historical factors. Traditionally, business risks and returns have been viewed in isolation. It is believed that business must be profitable, and risks are only a matter of the integrity of the businessman, so the requirement to maintain capital is a constraint on the personal credit of the businessman. Another aspect is that China has not developed a more mature capital market. Lack of market tools. Pricing, trading and risk management of equity.

It has been more than 20 years since China’s securities capital market started in the early 1990s. Although it has begun to take shape, its influence on the entire social economy is still very limited. First of all, the threshold is high, and various claims and The market instrument of equity is limited to thousands of listed companies. China's stock market itself lacks a money-making effect, making ordinary people's perception of equity investment even more negative.

As a tool for credit management, blockchain technology can build innovative trading models at low cost and automatically form a secondary trading market. It provides new opportunities to promote equity investment.

Bitcoin’s POW mining mode is a pure computing power game. If mining can be combined with business incubation, real capital functions can be achieved.

This is also the charm of the token economy. Through deterministic algorithms, ecological rights and interests are distributed, and at the same time, value is tempered through free market transactions. Convert future uncertainty into capital value. Form consensus on new wealth.

④ What is the principle of Bitcoin and blockchain and what is happening with mining machines?

Bitcoin is a digital currency generated based on a specific algorithm

Bitcoin is equivalent to digital gold. As a generally recognized equivalent, gold naturally has monetary properties and has been regarded as a currency in circulation since ancient times. Bitcoin was born in 2009. It was created by a person named Satoshi Nakamoto. As the earliest digital currency, it can be said to be worthless at the beginning of its creation. Until 2017, the highest trading price of Bitcoin exceeded 30,000. RMB and Bitcoin have become a valuable digital currency for the following reasons:

First of all, it is like gold. As a natural mineral, the total amount is limited. The same is true for Bitcoin. According to its own algorithm, it cannot be over-issued, so there will be no rapid devaluation of currency due to excessive currency issuance. Due to algorithm reasons, the number of Bitcoins is controlled to no more than 21 million, and it cannot be issued in large quantities, so that its value is guaranteed. .

⑤ What is blockchain mining? How is blockchain mining?

What is blockchain mining? How is blockchain mining< br />Before the rise of blockchain, miners specifically referred to workers digging coal mines. The collective impression was that they were covered in coal dust and were men with dark skin except for their clothes. After the birth of blockchainMiner is no longer just the abbreviation of coal miner, but has a whole new meaning: a person engaged in cryptocurrency mining.
For those who have not participated in mining, it may be difficult to understand blockchain mining, so today we will start with the most basic question: What is blockchain mining? How to mine blockchain?
What is blockchain mining?
There are two types of mining in the new era, the first is to mine Bitcoin. After each transaction occurs, it is not completed. The transaction data must be written into the database before it is established and the other party can actually receive the money. First, all transaction data will be sent to the miners, who are responsible for writing these transactions into the blockchain and completing mining to obtain profits.
The second type is to dig up copycats. Various “altcoins” such as Zcoin, Monero, Ethereum, Litecoin, and BitShares. After assembling a mining machine, connect to the designated mining pool and start computing at full load according to a specific algorithm. After completing one calculation cycle, you can obtain "one" virtual currency. Then put "this" currency on the online trading platform and cash out.

How to mine blockchain?
In the beginning, Bitcoin could be mined using a computer CPU. The founder of Bitcoin, Satoshi Nakamoto, used his computer CPU to mine it. The world’s first genesis block. However, the era of CPU mining has long passed, and now Bitcoin mining is the era of ASIC mining and large-scale cluster mining.
If you want to become a miner, it is actually relatively simple. You can just buy a special mining equipment and start mining. Mining does not require you to do it yourself. The computer actually performs specific calculations. For miners, it is enough to ensure the power supply and network connection of the mining machine.
Can blockchain mining still make money?
In the beginning, some people did get rich through blockchain mining, but as the number of miners increased, there was also great competition among miners. , profit margins are being compressed smaller and smaller. In addition, a machine that mines Bitcoin costs tens of thousands of dollars, and cannot dig out a single coin in a year. The input cost is high and the output is low. If the market conditions are unfavorable again, miners will Basically losing money.

Therefore, in addition to mining, more and more investors choose to invest in foreign exchange to make money. Unlike mining, the investment cost of foreign exchange is extremely low. For example, Juhui ggfx can be traded with a minimum of 8 US dollars. With long and short two-way operations, investors can make profits regardless of whether the market is rising or falling. It is also very convenient for people who are busy and want to invest and make money. If you download Juhui ggfx’s MT4 trading software to your mobile phone, you can learn about the latest market conditions and participate in transactions through your mobile phone at any time, and complete orders as quickly as seconds. It is simple and fast. , the efficiency of making money is extremely high, so in addition to mining, this is also a good way to get rich.
Mining is not an easy task. Mining consumes a lot of resources because the calculation difficulty of generating virtual currency is very high and it is constantly changing. After every 2016 data blocks are generated globally, mining virtual currency The difficulty of currency isIt will increase once, so ordinary people should consider all aspects before joining the ranks of miners.

⑥ Energy Blockchain Research丨The Development Process of Bitcoin Mining

Bitcoin has not yet reached the growth stage, but as the speed of Bitcoin mining begins to accelerate, the The industry is poised for substantial growth.

In October 2008, when Satoshi Nakamoto published a white paper detailing how to create a new currency system, no one expected that the market value of Bitcoin would soar to 850 billion in less than 13 years. Dollar. Additionally, Bitcoin spawned thousands of other types of cryptocurrencies, formed an entire financial services industry, and evolved into a new asset class that revolutionized money as we know it.

Our company has been involved in Bitcoin mining activities for seven years and has contributed to the development and adaptation of the industry. Below we’ll take a look at some of the lesser-known developments in Bitcoin mining and some of the trends that have a major impact on the industry.

The emergence of Bitcoin mining

Bitcoin is a decentralized currency system that functions like gold and is a limited commodity with a means of storing value. This means that Bitcoin has a limited supply, with only 21 million Bitcoins currently in existence, making it less susceptible to inflation. People who want to use Bitcoin are not subject to government oversight that has the power to change its value or determine users’ access rights.

So where does Bitcoin itself come from? Like gold, Bitcoin must be mined, but instead of using picks and shovels, you do it with computers.

Bitcoin is based on blockchain technology. Miners around the world compete to solve an algorithm so they can add a block to the blockchain. The first person to solve the algorithm can obtain the transaction fees of the block and a fixed reward for the issuance of new coins (currently 6.25 Bitcoins per block), which will increase the circulation of Bitcoin.

When Bitcoin was first created, mining was so easy that miners could mine from their kitchens using laptops equipped with standard central processing units. However, as more and more miners join, the competition for solving the problem becomes more and more fierce, which also means that miners need stronger data processing capabilities and newer hardware equipment. In order to efficiently run more powerful computers, the price of electricity began to be taken into account. Soon, due to the fierce competition in mining, individual mining was no longer profitable.

The birth of a multi-billion dollar industry

To be profitable, mining operations must be scaled up. Currently, new mining-specific hardware has appeared on the market, and miners have installed mining machines in trailers and warehouses so that large mining farms with thousands of mining machines can solve algorithm problems around the clock. The operation of large-scale mines includes layout and design, energy, software management, and hardware updates. Driven by these operational requirements, Bitcoin mining has rapidly developed into a multi-billion dollar industry.Yuan industry.

A report from ARK Invest shows that the cost of hardware to support the ecosystem is approximately $7.2 billion. Additionally, the report states, “Since the advent of Bitcoin-specific hardware in 2013, we believe there have been Billions of dollars were spent on design, production, and tape-out, spawning an industry dedicated to manufacturing this powerful and specialized hardware.

Bitcoin mining is complex but highly profitable. . Ark Investment estimates that miners can earn $15 billion in revenue from transaction fees and fixed Bitcoin rewards.

Competition spawns new hardware

Competition for Bitcoin mining It continues to intensify, but because Bitcoin is a finite commodity, the competition for mining is also limited. This means that the mining operation needs to run as fast as possible with high performance, so as to obtain rewards.

As the increasingly fierce competition in Bitcoin mining increased the requirements for computing power, the mining competition also became a competition for graphics cards, which are hardware that gamers usually use in high-end games. Later, application-specific integrated circuits Gradually replacing graphics cards, this is a type of hardware specifically used to mine cryptocurrency. It is the fastest and most efficient hardware in Bitcoin mining and is currently only used in mining.

But the hardware Relying on chips, although chip technology continues to accelerate, the supply of chips still exceeds demand. This means that mining operations need to be planned and upgraded in advance, and the necessary hardware is often sold out. For example, Bitmain is facing a shortage recently.

New technologies are most likely to be profitable

Similarly, Bitcoin mining needs to keep up with the pace of technological development and make mining hardware bigger, better, and faster, because once the efficiency lags, it will cause profits Damage. Today, technology continues to outpace innovation, so mining not only needs to keep up with the purchase of new hardware, but also the installation of new hardware quickly. This is because time is of the essence, and even a delay of just a few days can cause serious damage, so many Mining operations (such as our company's mining) are renting Boeing 747s to reduce transportation time.

The number of miners in the West is increasing

For a long time, more than half of the world's mining energy came from China, mainly because it is cheaper to set up factories in China and shipping is faster. But as China steps up its crackdown on Bitcoin mining, these advantages are disappearing. According to Wired magazine, “Bitcoin "The geography of mining may be changing," and the business may shift to places such as North America, Europe and Latin America. Miners also plan to look for mining sites in places such as the Nordic countries, Canada and the United States, where there is an abundance of cheap, sustainable energy. , such as wind energy, solar energy, water energy, etc.

The future of Bitcoin

Although Bitcoin has seen a lot of volatility recently (which is not new), the future of Bitcoin is bright Yes, its priceValues ​​will continue to rise and new investors will be attracted. As more people begin to understand Bitcoin, its origins and how it is mined, people will also find more value in Bitcoin.

⑦ How does mining make money (Part 1)

If you want to understand the status of mining in the blockchain industry, you must understand the upstream, middle and downstream of the entire blockchain industry. Have a general understanding.

Upstream, such as the production of coins such as Bitcoin and mining-related companies. Among them are enterprises that design and produce mining machines, as well as the construction of mines and power generation equipment, and the operation of mining pools. These are all upstream enterprises of the blockchain.

Midstream, the midstream of blockchain refers to the transaction link and storage link. Many centralized and decentralized exchanges, as well as wallet development for various currencies, are midstream companies in the blockchain industry.

Downstream, various applications relying on blockchain technology, whether it is the underlying protocol, basic chain or application chain, all belong to downstream enterprises.

In the upstream, midstream and downstream industries, each link has its own logic for making money, and the level of risk is naturally very different. Below we introduce the categories.

The first type of way to make money is simple investment or speculation, specifically buying blockchain assets in the secondary market. The threshold is the lowest and the entry capital requirements are very low, as long as you can use the exchange to buy coins. The risk is high, and whether the profit or loss depends heavily on personal judgment of the market.

The second type of way to make money is early risk investment in projects, which is ICO. The threshold is not high, but the risks are extremely high. Some make dozens of times or even hundreds or thousands of times, while others lose all their money. First, because the project is in its early stages and is still a long way from being successfully implemented, the risk of project success or failure is high. Second, many unscrupulous projects are simply meant to defraud money and have no intention of bringing the project to fruition.

The third way to make money is cross-market hedging and arbitrage, referred to as arbitrage. The risk is small, but the threshold is now relatively high. The income from brick-moving comes from the price imbalance in multiple markets. Now manual brick-moving has been gradually eliminated. Programmed brick-moving transactions and increasingly professional operations have higher technical thresholds.

The fourth type of way to make money is high-frequency quantitative trading, which is a single-market arbitrage method. Similar to moving bricks, the risk is low and the technical threshold is high. You need to be very familiar with both the development and trading systems to make a profit.

The fifth way to make money is to open an exchange. The threshold mainly comes from capital and technology, as well as operations. The main risk is regulatory and policy uncertainty.

The sixth way to make money is OTC trading. As the number of exchanges with OTC functions gradually increases, the profit margin for individuals is gradually decreasing.

The seventh category of money-making methods is the production of hardware such as mining machines and chips. Do it in the industrySome of the better ones include Bitmain, Avalon, BITFURY and other companies. Professional development skills are required to engage in this industry.

The eighth way to make money is to operate a mining pool. The threshold for a mining pool is mainly technology and miners’ computing power support.

The ninth category of ways to make money is program development, such as applications, quantitative trading programs, automatic trading tools, mining machine and mining pool program development, etc.

The tenth way to make money is mining. If Bitcoin is compared to currency, mining is the process of issuing currency. It is a low-risk, medium-yield investment category. The payback period of a Bitcoin mining machine is approximately 100 to 300 days, depending on the currency price. In the next article, we will explain the relevant knowledge of mining in detail.

⑧ What is blockchain mining and what does it do? Detailed introduction to blockchain and virtual currency

When Bitcoin was first released, people discovered that it was decentralized and not It is controlled by any center; it is completely open, except for the encryption of transaction information, the entire system information is highly transparent, and the technology is open source; security, as long as you cannot control %51 of all nodes, you cannot modify the data arbitrarily, which makes it relatively safe ; Independence, the entire model and Bitcoin do not rely on any third party, all nodes verify and exchange data within the system without any intervention

Here we explain in detail what blockchain technology is, to put it bluntly It’s block + chain, so what is “block”? What is a "chain" again?

A block is a ledger. Transaction accounting is completed by multiple nodes distributed in different places, and each node records a complete account, so they can all participate in supervising the legality of the transaction, and at the same time Can jointly testify for it

Each block contains the cryptographic hash of the previous block, the corresponding timestamp, and the transaction data (usually a hash value calculated using the Merkle tree algorithm) represents), this design makes the block content difficult to tamper with. Distributed ledgers connected by blockchain technology can effectively record transactions between two parties and permanently verify the transactions.

The function of the hash function h(): convert a string of any length into a fixed-length (for example, 256 bits) output. The output is also called a hash value. This output is irreversible

It is difficult to find two different x and y such that h(x) = h(y), that is, two different inputs, There will be different output. Theoretically, two different inputs may have different outputs, but this is almost impossible. For example, if an infinite space is mapped to a finite space, there must be a many-to-one situation. The theory exists, but there are no rules. It is guaranteed that you cannot find this result through any mathematical inference. Why is it 256 bits here? Isn't it longer? Because 256 bits are secure enough.

Split the ledger into blocks. For example, a piece of paper in a book is a block. Each block records transactions within a period of time, such as 10 minutes.

We divide Each piece of paper is compared to a block. A part of content is added to each block. We call it a block header, which records the hash value of the parent block. Each block stores the hash value of the parent block. , connect all blocks smoothly to form a blockchain

Record the hash value of block 1 to the block header of block 2. In this way, the block header of each block is recorded The hash value of the parent block, each block is linked in order, this is called a blockchain. The first block has no block header and is also called the genesis block

The blockchain is a ledger. Only when transactions occur in the ledger will the money in your account increase. If you need to make a transaction, you first need an account number and password. Just like your bank card has an account number and password, others can make a transfer to you. The account password on the block ledger is the public key and private key

Lao Wang (who already has a private key and a public key) wants to transfer 10 BTC to Zhang, which requires some operations

It is proved that Lao Wang himself issued the transfer signature function Sign (Lao Wang’s private key + Transfer information: Lao Wang transferred 10 BTC to Zhang San) = signature of this special account
The verification is that Lao Wang himself issued the transfer verification function Verify (Lao Wang’s address + Transfer details: Lao Wang transferred 10 BTC to Zhang San) + Signature of this transfer) = true
Once the transfer is recorded in the block, no one can change it. Zhang San will increase it by 10 BTC, and Lao Wang will decrease it by 10 BTC accordingly. The entire operation is automatic, such as your wallet The app will help you do this. The app knows your private key, you tell the wallet the transaction content, the wallet signature is announced to the entire network, and it waits for others to verify the transaction

Centralized accounting The efficiency will be higher. Banks, governments or Alipay will keep accounts for you, which is very reliable, because they can't touch your money unless they have your private key

There are some disadvantages in centralized accounting< /p>

In decentralization, everyone can keep accounts, and everyone can keep a complete ledger. Anyone can download open source programs, participate in Bitcoin's p2p network, monitor transactions sent from all over the world, become an accounting node, and participate in accounting. Suppose Xiaoyi releases a transaction and broadcasts it to the entire network, and accounting node A listens. When this transaction arrives, A verifies that the transaction bit is true and puts it into the transaction pool to continue to spread to other nodes. Because it is spread through the network, the transaction pools of different accounting nodes are not necessarily the same at the same time. Every 10 minutes, from all accounting nodes Among the nodes, one is selected according to a certain method, and after verifying that the transaction of this node is true,Then compare the transaction records in the selected node's transaction pool with the transaction records in the transaction pool of your own (A) node. After the comparison, you will delete the transactions recorded by the selected accounting node in your own transaction pool. Do not move and continue accounting, waiting for the next selection. Every 10 minutes is a cycle. During this 10 minutes, all accounting nodes will record accounts normally. After 10 minutes, a node will be selected to treat the transactions in its transaction pool as a new Block, this block comes from the transaction pool of an accounting node I randomly selected among all accounting nodes, and the cycle continues

The transaction is not completed when it is recorded, only when the transaction becomes Once a certain block is reached, the transaction is truly completed. This is a complete accounting process of decentralization. Your transaction will not be recorded immediately because the p2p network propagation takes time. If the node of the selected block has not received your transaction, the transaction will be not done. A block is generated every 10 minutes, but not all transactions within 10 minutes can be recorded. 10 minutes is just an average value

Due to the characteristics of decentralized accounting, accounting nodes with accounting rights will receive a 50BTC reward every ten minutes, which is about the same for every 210,000 blocks. In 4 years, the reward is halved. Bitcoin has been halved twice since its issuance. Then a new block is generated every ten minutes. The reward for this accounting node is 10.5 BTC. If it is halved every 4 years, the total number of BTC can be calculated. The amount is approximately 21 million, and it is expected to be mined in 2040. Recording the reward of a block is also the only way to issue Bitcoin. When BTC is mined, the only income that the accounting node can obtain is the transaction fee

Accounting nodes compete for accounting rights through questions,

Find a certain random number that makes the equation invalid
SHA256 hash function (random number + parent block hash value + Transactions in the transaction pool) A certain specified value)
There is no other solution except traversing the random numbers starting from 0 and trying luck. The process of solving the problem is also called mining, so the accounting node that solves this problem is also called mining. It’s called a miner. The faster you traverse random numbers, the greater the possibility of getting the accounting rights. This traversal speed is called computing power by mine bosses. In order to obtain this computing power, mine bosses will Purchase more mining machines with higher computing power

Whoever solves the problem correctly first will get the accounting rights. Accounting node A is the first to find the solution, which is announced to the entire network. After other nodes verify that it is correct, node A obtains the block, gains 12.5 BTC, and restarts a new round of calculation after the new block. This method is called (POW) allocating accounting rights

It usually takes about 10 minutes to solve this random number. 10 is not absolute, because the process of solving this problem is a process of luck. In response to changes in computing power in the future, Bitcoin willEvery 2016 blocks, about two weeks, the difficulty will be increased or decreased, so that the average block generation time is ten minutes

Each block contains the encrypted hash of the previous block, Corresponding timestamps and transaction data (usually represented by hash values ​​calculated using the Merkle tree algorithm), this design makes the block content difficult to tamper with. Distributed ledgers connected by blockchain technology can effectively record transactions between two parties and permanently verify the transactions.

Different from traditional stored data, each node of the blockchain stores complete data according to the block chain structure. Each node of the blockchain is independent and has equal status, relying on The consensus mechanism ensures storage consistency, while traditional distributed storage generally synchronizes data to other backup nodes through a central node.

Mahjong is a traditional Chinese blockchain project. A group of four miners work together. The miner who first collides with the correct hash value of 13 numbers can obtain the accounting rights and be rewarded.

Many people say that blockchain is a scam and Bitcoin is a scam. This may be a scam, but this technology has been widely recognized and applied. The cryptography knowledge involved in blockchain can only be used by ordinary people. Even if you don’t understand it, the most important thing is to look at the problem from a relatively rational perspective. Don’t let the wind be the rain.

There is something incredible about this technology. It maintains absolute order without a center or supervision. This is the trust that only needs to be established by everyone’s consensus. Bitcoin created this consensus. In the blockchain In the world everyone is fair and equal.

⑨ Waiting online, the principle of mining with mining machines

Mining with mining machines refers to the process in which users use specific hardware equipment (mining machines) to mine digital currencies. The working principle of a mining machine is: it uses specific software and hardware components to complete the mining process, using the processing power of the computer to solve complex mathematical problems in the digital currency network, thereby obtaining digital currency rewards.

The specific process of miner mining is: first, the miner will obtain new transactions from the blockchain network and combine them into a new block; then, the miner will calculate the new block The hash value, that is, the block header; then, the miner will check whether the hash value of the new block meets the requirements of the blockchain network. If it meets the requirements, the miner can add the new block to the blockchain network; , the miner will receive certain digital currency rewards.

The principle of mining by mining machines is based on blockchain technology, which is a distributed ledger technology that can record all digital currency transactions and ensure that these transactions are safe and reliable. Blockchain technology is a distributed ledger technology that can record all digital currency transactions and ensure that these transactions are safe and reliable. The core principle of blockchain technology is: a network composed of mining machines and miners can be completed by using the processing power of computers.Solve complex mathematical problems and earn digital currency rewards.

The advantages of mining with mining machines are: it allows users to obtain digital currency rewards without worrying about security; it allows users to participate in digital currency transactions more conveniently; it allows users to participate in digital currency transactions more quickly; Earn digital currency rewards; it allows users to participate in digital currency transactions more safely.

The disadvantages of mining with mining machines also exist: mining with mining machines requires the purchase of professional hardcore equipment, and the prices of these equipment are relatively high; mining with mining machines requires a large amount of Electricity, and the electricity bill is relatively high; the computing power of mining machines is also limited, and the mining speed is relatively slow; the benefits of mining with mining machines are also limited, because the prices of digital currencies such as Bitcoin are also limited.

In short, mining machine mining is a technology that uses computer processing power to solve complex mathematical problems in the digital currency network to obtain digital currency rewards. It has the advantage of obtaining digital currency rewards. But there are also some disadvantages, such as high hardware purchase costs, large power consumption and limited benefits.

⑩ Can anyone tell me whether blockchain transaction mining will lose money?

Losing money is possible under any circumstances. There is no 100% guarantee in this world. Be able to identify investments that will make money.

With the rise in the price of Bitcoin, the mining industry has become a veritable "gold mine". The large influx of newcomers and retail investors has made the Bitcoin market

Coin mining machines are hard to come by.

It is precisely in the face of such a market that the price of Bitcoin mining machines has also begun to rise. Not only that, because the number of Bitcoins is becoming increasingly scarce

, so mining The difficulty is getting bigger and bigger, and now the production capacity of Bitcoin mining will gradually decrease.

When the revenue of the mining machine is not enough to pay for the electricity consumed, the currency price at this time is called the "shutdown currency price". The influencing factors include currency price, electricity consumption

price, mining Mining difficulty, etc., if the currency price falls below the "shutdown currency price", miners need to shut down the mining machine, otherwise they will lose money.

So, any industry has certain risks, and only when you devote yourself to this industry, that is, after you have a deep understanding

, will you know There are risks involved, and you need to bear these risks before you can continue to develop in this industry.

Blockchain mining:

In 2009, Satoshi Nakamoto invented Bitcoin and set a limit of 21 million Bitcoins. In the Bitcoin network, by participating in the production of blocks and providing proof of work (PoW), you can obtain rewards from the Bitcoin network. This process is mining.

The concept of "mining" is taken from the existing concepts in our real economic life, such as gold mining, silver mining, etc., because minerals are valuable

That's why people are driven toPay labor to dig.

Another important point in Bitcoin mining is that the miners participating in mining recognize the value of Bitcoin, and there are people in the market who are willing to mine the Bitcoin market

Spend money. So, Bitcoin mining makes sense.
